There is great photograph of Main Street showing the Hippodrome Theatre on the Library of Congress website. The Hippodrome can be seen at the extreme right of the photo, in the next block down from the Ellicott Building. The admission is advertised as 5 cents. Go to www.loc.gov./do a search for Main Street Buffalo (or similar) and there are multiple results/click on “Main Street, Buffalo N.Y.” for the photo.
